ASTM A36 is a mild carbon steel specified by the American Society for Testing and Materials, characterized by low carbon content and straightforward iron-manganese chemistry that prioritizes weldability and formability over high strength. It is the most widely used structural steel in North America, serving as the baseline material for bridges, buildings, towers, and machinery frames where moderate strength and excellent ductility are required. Engineers select A36 for its proven performance in welded construction, cost-effectiveness, ready availability, and reliable behavior under static loads; it remains the default choice for structural applications unless higher strength grades or corrosion resistance are specifically needed.
